SOLVED: I can't access from LG TV with Caddy

[Drake97]

Hello everyone,

As the title says, I can't access my content server from any LG TV, at the moment of entering the URL it stays on black screen as if it was thinking infinitely.

This happened since I followed a tutorial on how to activate the connection through a reverse proxy, in my case Caddy, and using duckdns as a dynamic dns server.
I can login on all the usual platforms, only on LG I can't and I don't know if it's because of Caddy, Duckdns or some configuration I have which is blocking access.

I checked the Jellyfin logs and there is nothing about it, it is as if it does not connect and I don't know what else I can do.

Any help is welcome and if you need logs or screenshots, just ask me.

Regards
